针对热工系统中普遍存在的一阶时滞、二阶时滞热工过程，提出以ITAE指标为目标函数，利用黄金分割法对IMC?PID的滤波器参数进行优化。首先，仿真研究了ITAE指标函数对滤波器参数呈单峰性的特点，然后采用黄金分割法对滤波器参数进行快速寻优，从而使系统响应达到最优性能指标。仿真结果表明，该方法能够快速地寻优出滤波器参数，对热工系统的控制研究以及运行操作人员具有一定的指导意义。

For the prevalent one order?delay plus dead time, second order?delay plus dead time thermal process, this paper proposes a method to ITAE index as an objective function, use the golden section method to optimize the IMC?PID filter parameters. First, simulation of the filter parameters ITAE index shows a single peak characteris?tics, then the study uses the golden section method for rapid optimization of the filter parameters, allowing the sys?tem to achieve optimal performance. Simulation results show that this method can quickly optimize the filter param?eters, which may provide guidance for research and operational control of the operator of thermal systems.
